Description

  The present invention relates to a probe information collecting system for collecting, from a plurality of vehicles, probe information acquired when the vehicle travels, such as vehicle speed information and position information, for example.

  Heretofore, as such a probe information collecting system, for example, as shown in Patent Document 1, there has been proposed one in which a center determines probe information to be acquired in a vehicle. In this system, the center determines the necessity of collecting probe information of each section for each time zone, and sets points for each time zone of each section in the point table according to the determination result. In addition, the center determines the planned traveling section and the planned traveling time of the vehicle based on the information of the departure place, the destination and the route received from the vehicle, and refers to the point table based on the determined information. Read out the set points. Then, the center determines a section in which the read point is equal to or more than a predetermined threshold as a target of acquisition of probe information. As a result, since each vehicle is limited to a section where probe information is acquired and a time zone is highly required, the frequency at which the probe information is collected from each vehicle to the center is reduced, and the communication cost is suppressed. Become.

  By the way, in the system described in the above-mentioned document, each vehicle side is made to search for a traveling route of a vehicle which is an object of acquisition of probe information. Therefore, for example, there has been a problem that it is difficult to efficiently collect probe information of a section required by the center, such as a section corresponding to a road link having a relatively high link cost on map data.

  The present invention has been made in view of such circumstances, and an object thereof is to provide a probe information collecting system capable of efficiently collecting probe information required by a probe information collecting system. It is in.

  A probe information collecting system for solving the above problems is a probe information collecting system for collecting probe information acquired when a vehicle is traveling from a plurality of vehicles, and a probe information storage unit for storing the probe information received from the vehicle A travel request route for managing, as a travel request route, a route composed of one or more sections on the map data for which collection of the probe information is required based on the probe information stored in the probe information storage unit The traveling from the departure place to the destination based on the management unit, information on the departure place and destination of the vehicle received from the vehicle, and the traveling required route managed by the traveling required route management unit A route calculation unit that calculates a travel route of a vehicle including a section that constitutes a required route, and the travel route calculated by the route calculation unit Among the sections included in the travel route calculated by the route calculation section, and a relatively high reward compared to other sections with respect to the section constituting the travel required route Remuneration information which is set and, when the vehicle having received the information on the travel route from the transmission unit travels the travel request route, issues, to the vehicle, a reward set in a section constituting the travel request route. And a management unit.

  According to the above configuration, the travel request route including one or more sections in which collection of the probe information is required is managed by the system that collects the probe information from the plurality of vehicles. Then, a route including a section that constitutes a travel request route is calculated on the system side as a travel route to be transmitted to the vehicle. This enables efficient collection of probe information required by the probe information collection system. Also, according to the above configuration, when the vehicle travels in a section where collection of probe information is required, a relatively high reward is paid to the vehicle as compared to when the vehicle travels in another section. publish. As a result, the driver of the vehicle is prompted to collect the probe information of the section that needs to be collected, so that the probe information of the section can be collected more efficiently.

The flowchart which shows the processing procedure of the collection processing of the probe information which the probe information collection system of the embodiment performs. The flowchart which shows the processing procedure of the collection processing of the probe information which the probe information collection system of the embodiment performs.

Hereinafter, an embodiment of a probe information collecting system will be described with reference to the drawings.
The probe information collection system of the present embodiment is configured by a center that manages traveling information of a plurality of vehicles. The center sets a traveling request route composed of one or more sections in which collection of a probe is required among sections on the map data based on probe information collected from a plurality of vehicles, and is set. The required route is accumulated in the traveling required route database. In addition, the center is configured to center the travel route of the vehicle including the section requiring the travel request route based on the information on the departure point and the destination of the vehicle received from the vehicle and the travel request route stored in the travel request route database. Calculated as a calculated route.

  At this time, the center calculates, as the center calculation route, a travel route of a vehicle, of the travel request routes accumulated in the travel request route database, overlapping all or part of the travel request route with a predetermined travel request route. Then, the center transmits the center calculation route thus calculated to the vehicle serving as the transmission source of the departure place and the destination. On the other hand, when the center calculation route received from the center is different from the planned travel route searched on the vehicle side, the vehicle route of the vehicle based on the center calculation route on condition that the driver of the vehicle obtained the consent. Perform guidance. Thereafter, when the vehicle travels on the center calculation route, a reward is issued to the vehicle based on the setting information of the reward set in the section which constitutes the travel request route included in the center calculation route.

  Specifically, as shown in FIG. 1, the vehicle 100 is provided with a navigation system 110 that guides the route of the vehicle 100. The navigation system 110 has a route search unit 112 for searching a planned travel route from the current position of the vehicle 100 specified through GPS (Global Positioning System) to a destination input through the input unit 111. . The route search unit 112 searches for a planned travel route on the map data registered in the map database 113 using the Dijkstra method or the like while referring to the link cost set for each road link.

  In addition, the vehicle 100 includes a probe information acquisition unit 120 that acquires probe information used for generation of traffic information by the center 200, such as vehicle speed information and vehicle position information, when the vehicle 100 travels. For example, in addition to the above-described GPS, the probe information acquisition unit 120 includes a vehicle speed sensor that detects the speed of the vehicle, and an on-vehicle camera that captures an image of the interior of the vehicle or around the vehicle. Then, the probe information acquired through the probe information acquisition unit 120 is sent to the probe information management unit 130.

  The probe information management unit 130 stores the probe information sent from the probe information acquisition unit 120 in the probe information database 131. Further, the probe information management unit 130 extracts probe information not transmitted to the center 200 among the probe information stored in the probe information database 131. Then, the probe information management unit 130 transfers the probe information thus extracted from the probe information database 131 to the in-vehicle communication device 140.

  The on-vehicle communication device 140 transfers various information including the information on the departure point and the destination of the vehicle set by the navigation system 110 and the above-described probe information to the center 200 by wireless communication.

  On the other hand, the center 200 has a center communication unit 210 that communicates with the in-vehicle communication unit 140. The center communication device 210 transfers the probe information received from the in-vehicle communication device 140 to the probe information management unit 220. Then, the probe information management unit 220 stores the probe information transferred from the center communication device 210 in the probe information database 221.

  The probe information thus stored in the probe information database 221 is transferred from the probe information management unit 220 to the traveling request route management unit 230. The travel request route management unit 230, based on the probe information transferred from the probe information management unit 220, among the sections on the map data registered in the map database 240, a section without probe information, another section with probe information A section having a smaller number of sections compared with the section and a section in which the update time of the probe information is old and the information freshness is low are extracted. Then, the travel request route management unit 230 sets the section extracted in this way as a travel request route composed of one or more sections where collection of probe information is required, and the travel request route is set as a travel request. It is stored in the route database 231. Note that the sections that make up the travel request route do not necessarily have to be sections where the latest probe information is lacking, and for example, sections where the need for updating probe information is particularly high, such as sections where traffic congestion frequently occurs. The travel request route may be set in the form of inclusion.

  Further, the center communication device 210 transfers the information on the departure place and the destination of the vehicle received from the vehicle 100 to the route calculation unit 250. Then, when the information regarding the departure place and the destination of the vehicle is transferred from the center communication device 210, the route calculation unit 250 narrows down a group of routes from the departure place to the destination while referring to the map database 240. At this time, in addition to the shortest route from the departure place to the destination, the route calculation unit 250 may, for example, a route that does not exceed twice the shortest distance or a predicted travel time of 1.5 The route group is narrowed down to include routes that satisfy preset conditions, such as routes that do not exceed double.

  In addition, the route calculation unit 250 acquires the traveling request route stored in the traveling request route database 231 through the traveling request route management unit 230. Then, the route calculation unit 250 compares the travel request route thus acquired with the route group narrowed down as described above, and in the route group narrowed down, the route calculated by overlapping all or part of the travel request route is a center calculation route. Calculated as a candidate for At this time, when there is only one candidate for the center calculation route, the route calculation unit 250 determines the route to be the candidate as the center calculation route. Further, when there are a plurality of center calculation route candidates, the route calculation unit 250 determines, for example, a route with the shortest travel time predicted among the candidates as the center calculation route.

  Further, the route calculation unit 250 transmits information on the center calculation route determined as described above to the center communication device 210. At this time, when there is no center calculation route candidate, the route calculation unit 250 transmits information on the center calculation route to the center communication device 210 as information indicating that. Then, the center communication device 210 transfers the information on the center calculation route received from the route calculation unit 250 to the route determination unit 114 through the on-vehicle communication device 140.

  When the information on the center calculation route received from the center 200 includes the center calculation route determined as described above, the route determination unit 114 compares the center calculation route and the planned travel route searched by the route search unit 112. Compare. When the center calculation route and the planned travel route are the same route, the route determination unit 114 executes route guidance of the vehicle based on the planned travel route. At this time, the route determination unit 114 performs route guidance of the vehicle through display of a guidance screen on the display unit 116 by the image processing unit 115 or output of voice guidance from the voice output unit 117.

  Further, when the center calculation route and the planned travel route are different routes, the route determination unit 114 causes the image processing unit 115 to display the proposal screen on the display unit 116 for the route guidance of the vehicle based on the center calculation route. Or, through the output of the voice proposal from the voice output unit 117. Then, when the input operation to accept such a proposal is performed from the driver through the input unit 111, the route determination unit 114 executes route guidance of the vehicle based on the center calculation route. On the other hand, when the input operation to the effect that the above-described proposal is not received is performed from the driver through the input unit 111, the route determination unit 114 performs route guidance of the vehicle based on the planned travel route. The route determination unit 114 executes route guidance of the vehicle based on the planned travel route even when the information on the center calculation route received from the center 200 does not include the center calculation route determined as described above.

  Thereafter, when the navigation system 110 is performing route guidance for the vehicle, the vehicle 100 periodically transmits the position information of the vehicle specified by the GPS to the center communication device 210 through the on-vehicle communication device 140. Further, the center communication device 210 transfers the position information of the vehicle periodically received from the vehicle 100 to the reward information management unit 260.

  Based on the position information of the vehicle transferred from the center communication device 210, the reward information management unit 260 analyzes the locus of the traveling route on which the vehicle 100 actually travels while referring to the map database 240. Further, the reward information management unit 260 compares the trajectory of the travel route analyzed in this way with the travel request route stored in the travel request route database 231, and determines whether there is a travel request route overlapping the trajectory of the travel route. Determine if Then, when there is a corresponding travel request route, the reward information management unit 260 refers to the reward information database 261 to check whether or not the reward is set in the section that constitutes the travel request route.

  The reward is, for example, available for discounting of communication charges and point service, and is set based on the route length of the travel request route and the difference in the amount of information of the probe information with the related route. Then, on the condition that the reward is set in the section making up the corresponding travel request route, the reward information management unit 260 issues issuance of the reward based on the set information from the center communication device 210 to the reward processing server 300 on condition that the reward is set in the section constituting the required travel request route. Notify against Thereafter, the reward information management unit 260 resets the setting information of the reward for the section making up the travel request route notified of the issuance of the reward.

  Next, as an operation example of the probe information collection system according to the present embodiment, specific processing is performed on processing for setting a reward for a travel request route, which is executed by the reward information management unit 260 of the center 200 in cooperation with the reward processing server 300. Explain the procedure.

First, as shown in FIG. 2, the reward processing server 300 transmits a setting request for reward to the center 200 (step S <b> 20).
Subsequently, when the reward information management unit 260 of the center 200 receives a setting request for a reward from the reward processing server 300 (step S10), the reward information management unit 260 probes the probe information for the traveling request route instructed by the setting request from the probe information database 221. It reads out through the information management unit 220 (step S11).

  Then, based on the probe information read in the previous step S11, the reward information management unit 260 of the center 200 creates setting information of the reward for the traveling required route (step S12).

  Then, when there is a traveling required route for which the remuneration is to be set (step S13 = YES), the remuneration information management unit 260 of the center 200 sets the remuneration for the section constituting the corresponding traveling required route (step S13 = YES). Step S14), the process proceeds to step S15.

  On the other hand, when there is no travel request route to which a reward is to be set (step S13 = NO), the reward information management unit 260 of the center 200 shifts the process to step S15 without passing through the process of step S14. .

  Then, in step S15, the reward information management unit 260 of the center 200 transmits the reward setting result for the traveling required route to the reward processing server 300, and then ends the reward setting process shown in FIG.

  Further, when the reward processing server 300 receives the setting result of the reward for the traveling required route from the center 200 (step S21), the reward processing server 300 registers the received setting result of the reward in its own database and then the reward shown in FIG. Finish the setting process of.

  Next, as an operation example of the probe information collection system according to the present embodiment, a specific processing procedure of probe information collection processing performed by the center 200 in cooperation with the vehicle 100 will be described.

First, as shown in FIG. 3, the vehicle 100 sets information on the departure place and the destination of the vehicle through the navigation system 110 (step S30).
Then, the vehicle 100 transmits the information on the departure place and the destination of the vehicle set in the previous step S30 to the center 200 through the on-vehicle communication device 140 (step S31).

  On the other hand, when the center 200 receives the information on the departure place and the destination of the vehicle from the vehicle 100 (step S50 = YES), the route from the departure place to the destination satisfying the preset condition based on the received information. The groups are narrowed down through the route calculation unit 250 (step S51).

  Subsequently, the center 200 acquires the traveling required route stored in the traveling required route database 231 through the traveling required route management unit 230. Further, the center 200 compares the travel request route thus acquired with the route group narrowed down in the previous step S51, and calculates a candidate for the center calculation route through the route calculation unit 250 based on the comparison result (step S52) .

  Then, next, when the center 200 has a candidate for the center calculation route calculated in the previous step S 52 (step S 53 = YES), the center calculation taking into consideration the traveling time etc. predicted from among the candidate routes. A route is determined through the route calculation unit 250 (step S54).

  On the other hand, when there is no center calculation route candidate calculated in the previous step S52 (step S53 = NO), the center 200 sets information indicating that as the information on the center calculation route.

Thereafter, the center 200 transmits information on the center calculation route to the vehicle 100 through the center communication device 210 (step S55).
On the other hand, the vehicle 100 transmits information on the departure place and the destination of the vehicle to the center 200 in the previous step S31, and then calculates a planned traveling route from the departure place of the vehicle to the destination through the route search unit 112 Step S32).

  Subsequently, when the vehicle 100 receives the information on the center calculation route transmitted from the center 200 in the previous step S55 (step S33 = YES), whether or not the received information includes the center calculation route, The determination is made through the route determination unit 114 (step S34).

  Then, when the center calculation route is included in the information received in the previous step S33 (step S34 = YES), the vehicle 100 is a route in which the center calculation route is different from the planned travel route calculated in the previous step S33. It is determined through the path determination unit 114 whether or not it is (step S35).

  In this case, when vehicle 100 determines that the center calculation route and the planned travel route are different routes (step S35 = YES), the center calculation route is presented to the driver through display unit 116 or voice output unit 117 (step In step S36), for the route guidance of the vehicle based on the center calculated route, the presence or absence of the consent from the driver is confirmed (step S37).

  Then, when consent from the driver is obtained (step S37 = YES), the vehicle 100 executes route guidance of the vehicle based on the center calculation route through the display unit 116 or the voice output unit 117 (step S38).

  On the other hand, when the vehicle 100 does not obtain consent from the driver in the previous step S37 (step S37 = NO), the route guidance of the vehicle based on the planned travel route calculated in the previous step S32 is displayed on the display unit 116 or It is executed through the voice output unit 117 (step S39).

  Also, when the vehicle 100 does not include the center calculation route in the information received in the previous step S33 (step S34 = NO), or when the center calculation route and the planned travel route are the same route (step S35 = Even if the driver's consent is not obtained for the route guidance of the vehicle based on the center calculated route (step S37 = NO), the route of the vehicle based on the planned travel route calculated in the previous step S32 The guidance is executed through the display unit 116 or the voice output unit 117 (step S39).

  Thereafter, as shown in FIG. 4, the vehicle 100 transmits the probe information acquired through the probe information acquisition unit 120 at the time of route guidance of the vehicle to the center 200 through the in-vehicle communication device 140 (step S40).

  On the other hand, when the center 200 receives the probe information from the vehicle 100 (step S56), the center 200 stores the received probe information from the probe information management unit 220 in the probe information database 221 to update the probe information (step S57). .

  Then, the center 200 updates the travel request route stored in the travel request route database 231 through the travel request route management unit 230 along with the update of the probe information (step S58).

  Further, based on the position information of the vehicle periodically received from the vehicle 100, the center 200 analyzes the locus of the traveling route actually traveled by the vehicle 100 through the reward information management unit 260 while referring to the map database 240. (Step S59).

  Subsequently, the center 200 compares the trajectory of the traveling route analyzed in the previous step S59 with the traveling required route stored in the traveling required route database 231, and there is a traveling required route overlapping the trajectory of the traveling route. It is determined through the reward information management unit 260 (step S60).

  Then, next, when the corresponding travel request route exists (step S60 = YES), the center 200 refers to the reward information database 261 and determines whether the reward is set in the section constituting the travel request route. Is determined through the reward information management unit 260 (step S61).

  Then, when the reward is set in the section constituting the corresponding travel request route (step S61 = YES), the center 200 notifies the reward processing server 300 of issuance of the reward from the reward information management unit 260 (step S61). Step S62).

  Thereafter, the center 200 erases the setting information of the reward regarding the section constituting the corresponding travel request route from the reward information database 261 through the reward information management unit 260 (step S63), and the probe information shown in FIG. 3 and FIG. Finish the collection process of

  On the other hand, the center 200 does not have a corresponding traveling required route in the previous step S60 (step S60 = NO), or the reward is not set to the corresponding traveling required route in the previous step S61 (step S61). = NO), the probe information collection process shown in FIG. 3 and FIG. 4 ends without passing through the processes of step S62 to step S63.

Next, the operation of the probe information collecting system of the present embodiment will be described.
Generally, when the center 200 collects probe information from a plurality of vehicles 100, when the vehicle searches for a traveling route along which each vehicle 100 travels, for example, it copes with a road link whose link cost is relatively high on map data. It becomes difficult to collect probe information of a section which is hard to be searched as a travel route on the vehicle side, such as a section to be collected, with sufficient frequency.

  In this respect, in the present embodiment, based on the probe information collected by the center 200 from the plurality of vehicles 100, the travel request route including one or more sections in which collection of probe information is required is managed. . Then, the center 200 calculates, as a center calculation route, a route in which all or part of the travel request routes overlap. In this case, for example, in addition to the shortest route from the departure point to the destination, the center calculation route is a route that does not exceed twice the shortest distance, or 1.5 times the predicted travel time. A route that does not exceed the route, which satisfies the preset conditions, and includes a section that the center 200 needs to collect, such as a section that is difficult to travel only by the search on the vehicle 100 side. Then, the center 200 transmits the center calculation route thus calculated to the vehicle 100, and realizes route guidance of the vehicle based on the center calculation route in the vehicle 100. Thereby, it becomes possible to collect probe information efficiently compared with the case where probe information is collected only from the section included in the traveling route which vehicle 100 searched.

As described above, according to the above-described embodiment, the following effects can be obtained.
(1) The center 200 manages a section which is a target of collecting probe information. As a result, it is possible to efficiently collect probe information of a section required by the center 200, such as a section that is difficult to travel only by a search on the vehicle 100 side.

  (2) When the vehicle 100 travels in a section where probe information is required, the center 200 pays a relatively high reward for the vehicle 100 compared to when the vehicle 100 travels in another section. Issue As a result, the driver of the vehicle is prompted to collect the probe information of the section that needs to be collected, so that the probe information of the section can be collected more efficiently.

The above embodiment can also be implemented in the following form.
In the above embodiment, the reward is set only in the section for which the probe information is to be collected. In addition to this, a reward may be set to a section which is not a target of probe information collection. In this case, a reward relatively higher than that of the other sections may be set for the section for which probe information is to be collected.

  In the above embodiment, the case where the reward is set for the section corresponding to the road link has been described as an example. Alternatively, or in addition to this, a reward may be set for a specific point on map data, such as, for example, a point of interest (POI).

  In the above embodiment, the navigation system 110 mounted on the vehicle 100 transmits the information on the starting point and the destination of the vehicle to the center 200. However, a portable information terminal or the like communicably connected to the in-vehicle apparatus can also be applied as a main body of transmission of information on the departure place and the destination of the vehicle.

  In the above embodiment, the case where the owner of the vehicle and the user of the vehicle are the same has been described as an example. However, it is possible to apply the present invention even when the owner of the vehicle and the user of the vehicle are different, for example, when using a taxi. In this case, for example, a navigation system mounted on a vehicle from a portable information terminal possessed by a user of the vehicle or a portable information terminal possessed by the owner of the vehicle communicably connected to the in-vehicle apparatus starts the vehicle And information on the destination may be transferred. In addition, the portable information terminal carried by the user of the vehicle may be directly connected to the in-vehicle apparatus. Then, the reward issued to the owner of the vehicle as the vehicle travels may be distributed to the user of the vehicle.
